What makes Zillow.com interesting is what it offers: an easy way to find out the value of your home. Using your choice of satellite images or drawings, you can see what your neighbors' homes sold for, when they sold it, and more.

It's still in beta, but so far, the reviews have been somewhat favorable. But you should not rely on it. There is still some data missing.
